Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search), marked decrease (Expand Search)
large decrease » larger decrease (Expand Search), marked decrease (Expand Search), large increases (Expand Search)
laser decrease » larger decrease (Expand Search), linear decrease (Expand Search), water decreases (Expand Search)
a largest » _ largest (Expand Search), a latest (Expand Search)
a large » _ large (Expand Search)
a laser » _ laser (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( a largest decrease ) OR ( a large decrease ))) OR ( a laser decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( a largest decrease ) OR ( a large decrease ))) OR ( a laser decrease ))*.
